Abstract
The invention includes coupling compounds, rubber compositions, and tires. The coupling compounds can, for example, be used to couple to silica filler. Rubber compositions can comprise the coupling compound and polymers. Polymers can be homopolymers, copolymers and terpolymers, and can include repeat units provided from conjugated diene monomers. Tires and various parts of tires can be made from those rubber compositions.
